If the vli library or header file could not be found, then a 
vtkVolumeProMapper (which doesn't actually render anything) will be 
returned instead of a vtkOpenGLVolumeProMapper.  Call 
vtkVolumeProMapper::GetClassName to find out what the New method created.

The only assumption that is made concerns the end of the path where the 
vli.h header file is located.  The end of the path for the VolumePro500 is 
assumed to be VolumePro\Inc\vli.h on Windows or vli/include/vli.h on Unix.

Assuming you are using the new VTK tree (using CMake, etc.) first set 
VTK_USE_VOLUMEPRO to ON.  Then, specify the path to the vli library in 
VLI_LIBRARY_FOR_VG500.  For the vli.h header file, you need to specify the 
path to VolumePro/inc/vli.h (or vli/include/vli.h) in 
VLI_INCLUDE_PATH_FOR_VG500.  Make sure that the values for these variables 
are correct.
